The role of vintage as a guide to the character

With the passing of time, changes take place in a wine and therefore the age of a wine, with specific reference to vintage, can serve as a guide to another aspect of its character. 

The vintage which appears on the label of a wine confirms that at least 85% of the content of that bottle is from that specific claimed year. Vintage may only be indicated on a label if the wine is certified by the Wine and Spirit Board.
